To ally who/fairway concern:

drain. pipe Ml 'of any suitable. construction.'

lThewater is drawn from the tank G- at H.'

osite sides' at intervals, as indicated at e'.-

itting .over the pipe is .a copper hood FY .which has .lowerianges at fromwhich the l 'wa-ter flows in sheet or'ram form. In this manner, the lateral jets from E are caused `tri-spread andthe water leaves the edges f ina thin sheet of rain entirel .across the compartment A.' Instead "of ringing' the edges ffnear' together, theyvmay e kept a art as shown in Fig.7, so 'that two disinct sheets of. water are formed separated i ybody of water. Toinsure: these sheets of water being uniform, I. prefer to rovide' the edges f with line'corrugations FT as .shown Ain Figs'. Tand 8, to cause 1a multiplicityof closely arrangedr lines 4of dro s like -rain in sheet forin.-` This gives `the est results in; i

The suctionfof. thefan D causes the air to enterv thef compartment A and-pass-throu h the'sheets ofwater falling therein, 'as in i,- .cated-'bythe arrow.- The air is by this washed, and the water-laden air thus promeans propelled through the apparatus. and

Ordinarily, I

prefer three vertical rows of these troughshaped bars as indicated in Fig. 1, but one or more sets may be. employed, as preferred. Furthermorajl prefer to stagger the troughshaped bars,-.so that the au' striking the front face of'the4 bar i'iext to the com art- I j ment A will be deflected under the sai bar and strike the inclined face of the next bar at a slightly lower level, and so onwith successive ` ars. ',.There is a separation between the bars'of' each vvertical Arow to and free distribution of the -air to meet'any issomewhat lower than the most distant end. 'for the purpose of causing the water to flow derence of obstruction by excessive water dropping from any bar, as itis desirable to keep the resistance to thepassage of the air washmg and scouring.

downv to a minimum consistent with proper bars wil be better understood by re erence to Figs. 4, 5 andv. In Fig. 4, the 'plate K is l removed, and the endview of the barsis 'shown and these ap ear slightly in perspective because lthe en nearest to the observer toward the observer and toward the plate K 'when in lace. These trough-shaped -bars are forme of two lates which are united at the bottom by aange and. rivets c. lThe distant ends of these plates are preferably ilanged as atC by which they are -riveted to the wall vof the :chamber B. The opposite ends of the plates constituting the troughsha ed bar are flanged asat 1Cz for being riveted) to the plate AK. Furthermore, these iian es C2 do not extend to the bottomof the bar ut leave an opening C3 which comes in alinementwith the openingM in the plate K to allow the free'escape of water collected in the trough-shaped bar. These flanges may be vformed in'any other convenient manner'. y Fromv the above* description andas illustrated in the drawings, it will be seen that these transverse bars are trough-shaped on f the upper side to carry off the water and are V-shaped onf the lower side to present oblique surfaces against which the moist air impinges and travels. The general cross 4 section of the bars is ll-shaped.

In the preferred form of my improvement, I provide the flattened lower art C1L of one oi'. the lates and which with t e lower edge of the s oulder Cof the other plate provides permit the full.

The s ecific construction of myim roved .seater a gutter or groove S which acts as an obst/rue# tion for the passage of the water from below the inclined face of the bar, preventing it from being forced up the inclined face at the rear. This water which is caught by the gutter Sor shoulder part C5 will tend to fall into the trough-shaped bar immediately be low, and from the interior of this bar it will flow transversely and pass out of the aperture M into the chamber L and thence downward into the tank G. Where there is notan excess of water caught by the utterS, it will run alon(g the lower edge of t e shouldered portion 5 to the' lower part of the bar and thence run downward upon the inside of the plate K and out of the aperture M of the bar next below. By means of the surface presented by the under part of the bar, the water is'.l extracted from the air, so that by the successive impinging of the air upon the different vertical rows o bars, the excess of water is fully removed and the air passes to the blower D with only a reasonable humidity.. The more vertical rows of the bars yC which are ein loyed, the drier will be the air that leaves t e machine, up to the maximum humidity condition for any. temperature at which the air may be.

By examining Fig. 4, it will be observed that the bars of each row are staggered somewhat with the bars of the adjacent rows so that the air passing under the bottom of the bars of the front row will impinge upon the under surface `of the bars of the next row, and so on, with each row in succession. It is also evident that the air in passing below any bar in any particular row will tend to strike the inner obli ue surface of the next adjacent bar below 1n the .same row, and thereby give u 'an additional portion of its moisture. Tlns air will be directed obliquely upward bythis inner surface and will impinge against the under .surface of vthe bar of the next 'adjacentrow, and so lon re ieatedly.

While this staggering of the bars is preferlll able, it is not essentlal, and therefore I do not restrict myselfto this exact arrangement. It will also be observed that the shouldered parts C5 form a gutter S but do not, extend beyond the plane ofthe under oblique surface of the bar, and hence, while arresting the water which travels' over the surface of the bar, it does not materially `obstruct the free passage of the air, and is consequently, a desirable construction. If, however, it is desired to reduce the cost, the modified form shown in Fig. 6 may be cnrployed, in which case, the ilattened lower part C4 is omitted and the lower extension C5 is increased in length so as to project below the end of the front inclined surface of the bar and form in effect a gutter S. This, however, will Aobstruct the air more or less, and hence is not as desirable as the structure shown in Fig. 4t.

seais? In winter time, 'the air passing into the puriiier may be heated by means of heating pipes or coils I of anysuitable character and the amount of heat may be modified by providing a suitable by-pass valve J which-will permlt additional air to enter the puriier without assing through the heaters and which mingle Withtheheated airto reduce its temperature.

While, in general, the operation of the apparatus may be considered as havin the air Washed when passing through the s eets of water in the chamber A and dried by having the surplus water eliminated in passing over the bars C in thechamberB; it i-s evi-v Ydent that there Wil-l be more orless cleansing .taking place 4in the first Aand perhaps the second vertical rows of these bars from the fact that the bars will have layers'o water on their surfaces and the airwillbe caused to travel over andin contact withthesev layers of w-ater,' thereby producing more or less of a scrubbing effect. 'Any dirt .thus

" and also having their lower parts 'provided eliminated travels l ofl'V from.' the interior of the bars and `thence downward into theI tank. The general constructionY o fpthe appara? tus may be varied to suit thefconditlons of employment and in place ofian exhausting fan D, it is evident `thatthe air'may'be blown through thepurifier roger consisting parts Aand AB an .t
